The approximate line of best fit for the given data points, y = −2x − 2, is shown on the graph.

which is the residual value when x = –2?

a.–2

b.–1

c.1

d.2

the answer is: '-2'

Step-by-step explanation:

" A residual value is a difference between observed y-value(from scatter plot) and the predicted y-value( from regression equation line) ".

when we look at the scatter plot we see that the value of y at  is

,and when we substitute the value into the given equation

we get

so, the residual value is given as:

Hence, the residual value at x=-2 is -2.
